命令: mysql\_secure\_installation

	Enter current password for root:<–初次运行直接回车
	
	设置密码
	
	Set root password? [Y/n] <– 是否设置root用户密码，输入y并回车或直接回车
	
	New password: <– 设置root用户的密码
	Re-enter new password: <– 再输入一次你设置的密码
	
	其他配置
	
	Remove anonymous users? [Y/n] <– 是否删除匿名用户，回车
	
	Disallow root login remotely? [Y/n] <–是否禁止root远程登录,回车,
	
	Remove test database and access to it? [Y/n] <– 是否删除test数据库，回车
	
	Reload privilege tables now? [Y/n] <– 是否重新加载权限表，回车
	
	初始化MariaDB完成，接下来测试登录
	
	mysql -u root -p

# 先使用数据库
use mysql;

# 针对ip
create user 'root'@'192.168.10.10' identified by 'password';

#全部
 create user 'root'@'%' identified by 'password';

# 给用户最大权限
grant all privileges on *.* to 'root'@'%' identified by 'password';

# 给部分权限(test 数据库)

grant all privileges on test.* to 'root'@'%' identified by 'password' with grant option;

# 刷新权限表
	flush privileges;

# 查看
show grants for 'root'@'localhost';

首先安装依赖包

安装Python3.6所需要的依赖包：

	yum -y groupinstall "Development tools"
	
	yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

安装Python3.7还需额外安装依赖包：

	yum install libffi-devel -y

然后根据自己需求下载不同版本的Python3，我下载的是Python3.6.2

	wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz

	然后解压压缩包，进入该目录，安装Python3

	tar -xvJf  Python-3.6.2.tar.xz
	cd Python-3.6.2
	./configure --prefix=/usr/local/python3
	make && make install

最后创建软链接

	ln -s /usr/local/python3/bin/python3 /usr/bin/python3
	
	ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

a) 修改settings.py配置文件中的DEBUG=False模式，修改ALLOEWD_HOST=['*']

b) 修改工程目录下的urls.py

from django.views.static import serve

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^axf/', include('axf.urls', namespace='axf')),

	# 增加以下的url路由
    url(r'^static/(?P<path>.*)$', serve, {"document_root": settings.STATICFILES_DIRS[0]}),
	
   	url(r'^media/(?P<path>.*)$', serve, {"document_root": settings.MEDIA_ROOT}),


    url(r'^$', views.home)
]

# 验证用户的登录状态
   paths = ['/user/login/', '/user/register/',
            '/axf/market/', '/axf/marketparams/(\d+)/(\d+)/(\d+)/',
           '/static/[0-9a-zA-Z/\.]', '/media/[0-9a-zA-Z/\.]']

   for path in paths:
       if re.match(path, request.path):
           return None

a）添加nginx存储库
	
	yum install epel-release
	

b) 安装nginx

	yum install nginx

c) 运行nginx

Nginx不会自行启动。要运行Nginx
	
	systemctl start nginx

nginx的运行命令：

	 systemctl status nginx 查看nginx的状态
	 systemctl start/stop/enable/disable nginx 启动/关闭/设置开机启动/禁止开机启动
 

d）系统启动时启用Nginx
	
	systemctl enable nginx

e）如果您正在运行防火墙，请运行以下命令以允许HTTP和HTTPS通信：
	
	sudo firewall-cmd --permanent --zone=public --add-service=http 

	sudo firewall-cmd --permanent --zone=public --add-service=https

	sudo firewall-cmd --reload

<b>首先</b>：编写自己项目的nginx.conf文件如下：

每一个项目对应有一个自己定义的nginx的配置文件，比如爱鲜蜂项目，我定义为axfnginx.conf文件

	server {
	     listen       80;
	     server_name 39.104.176.9 localhost;
	
	     access_log /home/logs/access.log;
	     error_log /home/logs/error.log;
	
	     location / {
	         include uwsgi_params;
	         uwsgi_pass 127.0.0.1:8890;
	     }
	     location /static/ {
	         alias /home/src/axf/static/;
	         expires 30d;
	     }
	
	 }

<b>其次</b>：修改总的nginx的配置文件，让总的nginx文件包含我们自定义的项目的axfnginx.conf文件

总的nginx配置文件在：/etc/nginx/nginx.conf中

server {
    listen    80;
    server_name 47.106.180.185;

    access_log /home/logs/access.log;
    error_log /home/logs/error.log;

    location /static/ {
         alias /home/src/fresh_shop/static/;
    }

    location /media/ {
        alias /home/src/fresh_shop/media/;
    }

    location / {
        include uwsgi_params;
        uwsgi_pass 127.0.0.1:8890;
    }
}

[uwsgi]
master = true

processes = 4

chdir = /home/src/fresh_shop

pythonpath = /home/env/freshenv/bin/python3

module = fresh_shop.wsgi

socket = 127.0.0.1:8890

logto = /home/logs/uwsgi.log
